Quote: a writer for the Hong Kong-based newspaper South China Morning Post (publishing since 190 wrote a piece about his discomfort on the portrayal of Hong Kong in The Dark Knight.
The writer expresses sadness that money gets laundered in HK (it does, by much richer men than the mobsters of Gotham), a place where only criminals hang-out and that Nolan and crew only went for the Infernal Affairs HK mythology. (Which I prefer as its much closer to the truth than the Enter the Dragon comparison, no, nobody is kung fu fighting in the streets.)
Here's a clip of the Dark Knight crew in Hong Kong.
